Security Advisory for MiCC

Advisory ID: 15-0007
Publish Date: 2015-11-04
Revision: 1.0


MiCC does not modify the Microsoft IIS configuration during application installation. Without additional Microsoft IIS hardening, two vulnerabilities are present in CcmWeb which, if successfully exploited, could allow an attacker to read files or perform HTTP redirects.

Detailed Description

CcmWeb Unauthenticated Local File Inclusion

CcmWeb allows access to any file on the install drive using specially formulated URLs. This vulnerability could allow an attacker read access any file located on the same drive as the MiCC install drive. The attacker must know of the file structure and cannot list directories to discover it. The attacker can’t modify any files by exploiting this vulnerability.

CcmWeb open redirect

This vulnerability can allow an attacker to trick a user to navigate to an outside malicious web page by sending them a link.
